[单选题]
工作场所空气采样后，要求将采样体积换算成标准状况下的采样体积，它的换算公式为
A.V
=V
×［273/（273＋t）］×(P/101.3)
B.V=V＋［273/（273＋t）］×(P/101.3)
C.V=V×［273/（273＋t）］＋(P/101.3)
D.V=V×［273/（273＋t）］×(P/101.3)
E.V=V＋［273/（273＋t）］＋(P/101.3)
A.V=V×［273/（273＋t）］×(P/101.3)
B.V=V＋［273/（273＋t）］×(P/101.3)
C.V=V×［273/（273＋t）］＋(P/101.3)
D.V=V×［273/（273＋t）］×(P/101.3)
E.V=V＋［273/（273＋t）］＋(P/101.3)
